What to do with my music man?????

Hey everyone whats goin on? Well about year and half ago i got a beautiful music man sterling model. Plays super good, beautiful color and not a thing wrong with it. Then about 5 montsh ago i got a warwick customized 5..........wow. The best bass i have ever played and till this day i cant believe its all mine. I dont use my sterling model ever now. So heres the thing, should i sell it and if so how much money should i try to get for it, comes with music man hardcase shell. Try and trade it for something, bigger cab, bigger head. Or keep it? What would you guys do?
